That is amazing. Some genius modern-day engineers out there figured this out and then determined how to make it more efficient. While Thomas Edison gets the credit, and rightfully so, since his invention started the process, look how far we have come -- a century later. Edison deserves a lot of credit for saving many folks eyesight. I think they burnt whale blubber back then to illuminate a room.
LED's were terrible when they first hit the market, the light they emitted was an ugly gray. I have a box of incandescent bulbs in storage that I'm using up while I was waiting for them to improve the LED and get rid of the gray. Fascinating to learn how LED actually works.
